The or (||) operator is a fairly lenient operator which returns true when either of the two conditions in the group is true.  The if statement fails when both conditions are not satisfied and skips the respective code block until one of the grouped conditions is satisfied. The if with || operator can be written in symbol form:

if ((b > a) || (b > c)) {
 println("b is a winner")
}

The or operator can be written in word form:

if (b > a or b > c) {
    println("b is a winner")
}
